Subject: [PATCH v7 0/8] Migrate to mmdebstrap
Date: Wed, 1 Nov 2023 12:57:49 +0200 [thread overview]
Message-ID: <20231101105757.1988498-1-amikan@ilbers.de> (raw)
Switch Isar from debootstrap to mmdebstrap.
It makes isar-bootstrap target ~10..30% faster on both cross and native
rootfs types. Some measurements on qemuarm64-bookworm (required debs are
predownloaded and used during deb-dl-import):
- 20s vs 28s for "isar-bootstrap-host"
- 1m32s vs 1m48s for "isar-bootstrap-target
Also mmdebstrap support using SOURCE_DATE_EPOCH for images reproducibly
out of the box. But the main advantage is an ability to remove sudo for
debootstrapping later on (this needs "uidmap" package installed).
This change breaks Debian Buster support as host distro.
Changes since v6:
- Reorder patches.
Changes since v5:
- Improve keyring handling.
- Fix mmdebstrap hooks.
Changes since v4:
- Rebase on next.
- Migrate from apt-key to gpg.
- Fix Ubuntu and RPi targets.
- Cleanup debootstrap mentions.
- Fix commit messages.
Changes since v3:
- Rebase on latest next.
- Remove temporary patch 7 since kas:4.0 already includes mmdebstrap.
Changes since v2:
- Rebase on next.
- Fix commit messages.
- Update host requirements.
Changes since v1:
- Move mmdebstrap tmpdir to workdir.
- Fix kas building.
- Improve mounts cleanup.
